|From San Jose News, January 27, 1942|
This article says his property is now Live Oak Park, which is near to James Lick's home. But maybe that's not the same Live Oak Park.
There is a picture of his home that was "bounded by Guadalupe River, a line just north of San Carlos street, and what is now Spencer Avenue and West William Street." Definitely confusing directions! There is a Prevost Street near Spencer. Need old map!
What I found was a 1956 map pre-freeway map. It looks like it is exactly where the Children's Discovery Museum is located!
He died in 1869, according to the photo.
